5lbs. is a perfect mini-goal. I've tried for so long to lose weight, and everytime I've ever thought of how much I needed to lose---45, 65, 75, whatever---after a couple of weeks that number would look so daunting and I'd eventually give up. All I could think about was that high number and if I was only losing 1-2lbs. a week, I'd get so deflated. So I'd give up, regain, and gain more. This time, I have a total of 80+lbs. I need to lose, but I don't think about that number. I only think about 5lbs. I concentrate on the number 5, and because that number seems so low and easy, I'll see it through and make it. Then after I conquer that 5, I shoot for another 5. It's really helped to keep me on track this time around. I don't feel like I can't lose weight anymore. I know I can lose 5lbs.
You've got the right idea. 5lbs. is such an easier number to wrap your brain around. Once you reach it, pat yourself on the back, and shoot for another 5! Plus, with that kind of mini-goal, you'll be congratulating yourself and celebrating more often, which will make the weightloss journey so much more enjoyable
